对中国消费者非转基因菜油支付意愿的研究

有关中国消费者关于转基因食品接受度的资料非常有限.本文则首次尝试对中国消费者关于非转基因(non-GM)食用油的支付意愿(WTP)问题进行评估.通过对北京的671个消费者进行调查采访,运用假设评价方法(contingent valuation),可推导出消费者对非转基因菜油的支付意愿.为避免调查者无响应引起的偏差,运用了双变量概率选择模式对调查数据进行分析.研究结果表明,消费者对非转基因菜油的支付意愿受到了许多因素的影响,比如价格、风险意识、受教育程度和知识水平等等.计算所得的WTP显示,平均而言,被调查者愿意支付33%的额外费用来消费非转基因菜油.这一结果表明,中国消费者对转基因油持有相当怀疑的态度.     

Trapped bodies,moving minds: Uncertainty and migration among marginalised urban youth in Ethiopia

This paper from YOUR World Research highlights and explores the role of positive uncertainty in lives, strategies and transitions towards adulthood of marginalised children and youth in two urban locations in Ethiopia. Young men and women embraced notions of positive uncertainty, making journeys to street situations and internationally in search of more hopeful futures. While youth navigate uncertainty positively in the short term, the research suggests this is temporal and their agency relational and embedded. They seek support from peers but still want to belong and be accepted by their families and communities.
